You are now able to publish the project locally via sbt publishLocal. This allows you to reference the application as an sbt library dependency via "com.example" %% "my-aar-project" % "1.0.0" on your development machine. To make it publicly available, the sbt-sonatype plugin provides a convenient deployment process.

If the library project does not make use of views, you may also consider disabling the TR generation via typedResources in Android := false.
